In experiments at Kalyani during the winter months of 1987 and 1988, C. officinalis Lemon Queen seedlings were transplanted in early Nov. and were given 0, 10, 20 or 40 g N/msuperscript 2 and 0, 15 or 31 g P2O5/msuperscript 2. All plots received 10 mg K2O/msuperscript 2 and 5 kg FYM/msuperscript 2. Half of the N was applied 10 days after transplanting (DAT) and the remainder was applied in equal doses 40 and 70 DAT.
